0/0 Wfberg mvsmoa Attorney CONVERTIBLE CHAIR The invention thus consistsof a settee-bed of the kind described wherein a bed covering is attachedat one of its ends or sides to the base frame or seat portion and at itsopposite end or side to the backrest in such a manner that the backrestautomatically draws said bed covering over the seat portion and thebackrest when the settee-bed is converted into a bed and automaticallyfolds said bed covering back to its initial position when the backrestis swung back into the backrest or settee position.

FIELD OF THE INVENTION This invention relates to convertible settee-bedsof the type in which the back rest of a settee is movable to a positionin front of the seat portion to form a horizontal extension thereof andthus convert the settee into a bed.

BACKGROUND OF THE INVENTION The invention is concerned more particularlywith a setteebed of this general type in which the backrest is connectedwith a base frame by a pair of side arms which are pivotally connectedwith both the backrest and the base frame in such a manner that thebackrest can be swung from the backrest position at the back of the seatto the horizontal bed position in front of the seat.

With this type of settee-bed it is desirable to provide a bed coveringwhich covers the upholstery of the seat and backrest when in thehorizontal bed or reclining position and thereby protect the upholsterywhen the settee-bed is used as a bed and at the same time gives thereclining surface of the bed a smooth continuous appearance.

OBJECT OF THE INVENTION The object of the present invention is toprovide a setteebed with such a covering which is automatically drawnover the reclining surface of the bed by the backrest when the latter isswung into the horizontal bed position and automatically folded backwhen the backrest is swung back into the backrest position.

SUMMARY OF THE INVENTION The invention thus consists of a settee-bed ofthe kind described wherein a bed covering is attached at one of its endsor sides to the base frame or seat portion and at its opposite end orside to the backrest in such a manner that the backrest automaticallydraws said bed covering over the seat portion and the backrest when thesettee-bed is converted into a bed and automatically folds said bedcovering back to its initial position when the backrest is swung backinto the backrest or settee position.

DESCRIPTION OF THE DRAWING In order that the invention may be moreclearly understood one particular embodiment thereof will now bedescribed with reference to the accompanying diagrammatic drawing inwhich:

FIG. I is a part sectional side elevation of a settee-bed according tothe invention with the backrest in the settee position,

FIG. 2 is a similar view showing the backrest in an intermediateposotion during the conversion of the settee into a bed, and

FIG. 3 is a similar view after the settee has been converted into a bed.

SPECIFIC DESCRIPTION Referring to the drawing the settee-bed comprises abase frame 4 forming a seat which is provided with supporting legs 5, abackrest 6 which is connected with the base frame by a pair of side arms7 (only one being shown in the drawing) which are each pivoted at oneend to the base frame 4 at fulcrum 8 and at the other end to a fulcrumbracket 9 fixed at the top of the backrest 6 and dimensioned to allowthe backrest to be swung forwardly to the bed position (alternateposition). At the back of the settee-bed is fixed a backwall 11 havingat its top horizontal edge a transverse reinforcing bar 12 which forms asupport for the top of the backrest when the latter is in the setteeposition shown in FIG. 1. Rigidly fixed to the backrest 6 are legs (legmeans) 13 which support said backrest on the ground when the backrest isin the bed position shown in FIG. 3 and which abuts the backwall 11 tosupport the bottom of the backrest in correct position when in thesettee posi tion as shown in FIG. 1. It will be noted that when upwardlyextending backrest is in the settee position shown in FIG. 1 saidbackrest, the rear wall 11 and the side armrest portions 14 combine toform an enclosed compartment 20 which can be used to store bedding whenthe settee-bed is not in use as a bed.

The settee-bed is also provided with a cushion 15 or cushions overlyingthe generally horizontal upper surface for use when the settee-bed isused as a settee.

In accordance with the present invention the settee bed is provided witha bed covering 16 for covering and protecting the upholstery of the seatand backrest when in the bed position as shown in FIG. 3. The bedcovering 16 may consist of mattress ticking, relatively thin quilting orany other suitable material and is fitted to the settee-bed in such amanner that it is drawn over the horizontal reclining surface of theseat 4 and backrest 6 automatically when the backrest is swung from theposition shown in FIG. 1, through the position shown in FIG. 2 to theposition shown in FIG. 3, and is automatically returned to the positionshown in FIG. 1 when the backrest is swung back into the setteeposition.

In order to achieve this automatic positioning and re-positioning of thebed covering, one end or side edge of said covering is attached alongthe upper edge of the base frame 4 of the seat at 17 and its oppositeend or side edge is attached to the lower rear edge (as viewed inFIG. 1) of the backrest 6 at 18. The length or width of the coveringfrom the point of attachment 17 to the point of attachment 18, and themanner in which it is returned to the position shown in FIG. 1, is suchthat said covering is stretched tightly over the reclining surface ofthe bed in the position shown in FIG. 3 and when in the folded backposition shown in FIG. 1 the line of the fold, indicated at 19 in FIG.1, is in such a position that it is positioned rearwardly of the frontedge of the seat 4 and thus is invisible when the seat cushion orcushions 15 are placed on the seat. Thus the bed covering is completelyinvisible when the setteebed is in the settee position since the rearend or side is hidden with the enclosed compartment 20.

It should be noted that when the backrest 6 is swung from the FIG. 3 tothe FIG. 1 position the underside of the backrest engages the bedcovering just before it reaches the final position shown in FIG. 1 andthereby pushes part of the bed covering back into the enclosedcompartment 20.

The bed covering 16 is preferably detachably connected at 17 and 18 tothe base frame 4 and backrest 6 respectively so that it can easily beremoved for laundering or replacing. It may be detachably connected inany suitable manner, for example by lacing, the edges of the coveringbeing provided with a series of spaced eyelets through which a lace orcord can be threaded and tied to a suitable part of the base frame andbackrest.

What I claim is:

1. A piece of furniture, comprising a seat with a generally horizontalupper surface; a rear wall extending upwardly behind said seat, saidsurface extending transversely to said rear wall at its junctiontherewith; a backrest extending generally surface; leg means connectedwith said backrest on a rear surface thereof opposite said frontsurface, said leg means coming to rest on the ground in said alternateposition; and a bed covering fixedly attached at one of its ends to arear edge of said seat at said junction and at its opposite end to anunderside of said backrest near said leg means, said bed coveringoverlying said seat and said backrest in said alternate position andbeing folded over said seat in said seating position, with a foldlinelying between the forward and rearward edges of said upper surface ofsaid seat, and a cushion adapted to cover said foldline.

2. The piece of furniture defined in claim 1 wherein said bed coveringis detachably connected to said seat and said backrest with a lacing,the length of the bed covering between its points of attachment to saidseat and said backrest in said alternate position being arranged tomaintain the covering stripped tightly over said seat and said frontsurface of said backrest.
